Notes

Both secondary outputs (Sec1 and Sec2) are at 17.5 V, 0.10 A.
Inductance is for the primary, measured at 150 kHz, 0.1 Vrms, 0 Adc.
Isat: DC current that causes the primary inductance to drop 30% from its value without current.
Leakage Inductance is for the primary, measured with secondary windings shorted together.
2200 Vrms / 3111 VDC , one minute isolation (hipot) between primary and secondary windings.
